Hello JMHO,
I still keep most of my finds, But that depends on the type of property.
In my 22 plus years of metal detecting, I've never been booted from a property for giving coins or relics back to the property owner, Always had an open door to return in the future.
In this case, The property has allot of historical interest. The site is recorded in Ca. history books and is considered one of if not the most populated 1850's China Gold town settlements throughout California, Truly a busy settlement with allot of pioneer traffic. These finds MUST go back to the owner so he can pass the displayed finds to his children and they do theirs from one generation to the next, The owner understands this and I do as well, He is very appreciative to have me fulfill this commitment.
Metal detecting is a hobby, At least it is for most. Not a business and like most hobbies require allot of time and money. My approach opens up territory many can only dream of detecting, Never a dull moment and I do constantly locate old lost settlements of long ago and have many more to find in the future.
Locating an old lost settlement through reams of information and countless hours of research and then getting the proper permission of recovering finds are the moments I relish the most, It's part of the hobby and for me locating an old settlement or making the fine is far more important than the find itself.....Plus, I deal with a handshake and not need anything in writing.
Once a person gets to the point that making the fine is far more meaningful than the fine itself, He/She will enjoy the hobby even more, I hope someday you'll experience what I am saying here
HH,
Paul (Ca)
